SASH MOUNTING Filed March l5, 1947 2 Sheets-Sheet l IN V EN TOR. PAUL F. GERKEN BY M P. F. GERKEN March 13, 1951 SASH MOUNTING 2 sheets-sheet 2 Filed March 15, 1947 INVENTOR. I PAUL F. GERKEN Patented Mar. 13, 1951 UNITED STATES PATENT OFFICE 3 Claims.

My invention relates to sash mountings, more particularly to sash mountings for double hung windows, and included in the objects of my invention are:

First, to provide a sash mounting which enables double hung windows to be raised or lowered or adjusted to any position with a minimum of effort.

Second, to provide a sash mounting which ls particularly inexpensive to manufacture and readily incorporated in a window frame.

Third, to provide a sash mounting which is so arranged that the window sash may be readily removed for cleaning or repainting, and the sash mounting itself may be readily removed for repair.

Fourth, to provide a sash mounting whereby the bearing corners of double hung window sashes are metal sheathed by novelly arranged bearing plates designed to protect the window sash from 3-3 of Figure l, showing particularly the removable side rail and the window suspension means, the window sash being omitted.

Figure 4 is a side view of one of the window sash stirrup plates.

Figure 5 is a fragmentary edge view of the upper corner of one of the window sashes showing a, bearing plate thereon.

Figure 6 is a fragmentary sectional view thereof taken through 6--6 of Figure 5.

Figure 7 is a fragmentary sectional view thereof taken through 'I-l of Figure 5.

Figure 8 is a fragmentary elevational view of the removable stop employed to permit removal of the window sash.

Figure 9 is a fragmentary sectional view thereof through 9-9 of Figure 8.

Figure 10 is a fragmentary substantially diagrammatical view illustrating the removable separator strip employed to permit removal of the Window sashes.

Figure 11 is a similar substantially diagrammatical and sectional view illustrating the manner in which the removable side rail is mounted in the window frame.

My sash mounting is particularly designed for use in conjunction with double hung window sashes, designated I and 2. The window sashes are adapted to slide within a window frame which includes a pair of vertical side rails 3 and 4, sill 5, and a top rail 6.

Stops or guides 1 are provided along the outer edges of the side rails 3 and 4. These serve to guide the outer or'normally upper window sash I. The outer side of the window frame is provided with a suitable outside molding 8 or other conventional trim, and the inner side of the Window frame is provided with inside molding 9 or other suitable finish.

The side rail 4 is covered by a removable side rail Ill which carries a, iixed separator strip II and fixed inner stop I2 so as to define with the outside stop 'I a pair of channels or tracks to guide vertically the window sashes I and 2,. The lower extremity of the removable side rail I is provided with one or more retainer pins I3, adapted to nt into the sill 5, or other removable securing means may be employed. The upper extremity of the removable side rail IIJ is releasably retained in place by a leaf spring I4 secured to the top rail 6 and having a free end which tends to bear endwise against the upper portion of the side rail IIJ, all as shown best in Figure 11.

The opposite side rail 3 is provided with a removable separator strip I5 located between the window sashes I and 2. The removable separator strip may be held in much the same manner as the side rail I9; that is, the lower extremity of the separator strip I5 may be provided with a pin I5 or other means for interlocking with the sill 5, and a retainer spring I'I may be employed to latch the upper extremity of the separator strip, all as shown best in Figure 10.

The side rail 3 also carries a divided stop including a fixed lower section I8 and a removableV upper section I9. The two sections are provided with confronting Il-shaped ends 29 so shaped that the lower end of the upper section wedges behind the lower section. A retainer clip 2l fastened in the top rail 9 retains the removable upper section I9 in place, all as shown in Figures 8 and 9.

The side rail 4 and the overlying removable side `rail Ill are provided with mating grooves 23 which form vertical passages adapted to receive coil springs 24 anchored to the upper end of the side rail I0. The lower half of each groove or 3 passageway 23 is provided with a slot 25 extending through the side rail l0.

A pair of stirrup plates 2G are adapted to ride on the side rail l0. Each stirrup plate is preterably formed of spring material and is normally slightly bowed, as shown in Figure 4. The lower extremity of each stirrup plate is provided with an extension which ts under the window sash l or 2, as the case may be. Each stirrup plate thus occupies apositio'n interposed between an edge of its corresponding window and the side rail lll. Each stirrup :plate is provided with an a'rn 2l which extends through the corresponding slot 25 and is attached to the lower or free end f'the corresponding spring 24.

The corner of each window sash diagonally from its stirrup plate 26 is provided 'with a bear'- ing plate 28. Each bearing plate includes a key lug 29 which is adapted to project into and be retained by a tting 30 secured in the window sash. As shown in Figures 5, 6 and 7, the Yifetainer fitting 3i) is in the iorm `of a U-shaped sheet metal member, the legs of which are ldriven into the window sash and the web of which is provided with a slot so arranged with respectto the key lug is that the key lug may be inserted by turning the bearing plate 28 at right angles to the window sash and be retained when vthe bearing plate is placed` parallel with the sash. Each bearing plate 28 is formed of spring material and bowed so as to exert a side pressure on the adjacent side rail.

The side thrust exerted by the bearing plates 22 and stirrup plates 26 is ,Such as t0 counteract to a large extent the turning moment applied to the window by reason of the fact that the window is supported by one lower corner.

It should be observed however, that in place of the bearing plates 28, two sets of stirrupplates may be used, one under each'lower corner. of each window sash.

The window sashes may be removed by rst removing the upper section I9 o the removable stop, as indicated by dotted lines in Figure 1, then lifting the lower sash 2 until above the fixed lower section IS, whereupon the sash may be pivoted outwardly and slipped from its stirrup plate 26. The upper or outer sash lis then removed by rst removing the separator stripfl as indicated in Figure l0. The window sash l can then be pivoted and removed. After removingthe Windows, the side rail l may be unlatched and removed. The window is assembled by reversing this procedure.

Many kother embodiments of the invention may be resorted to without departing from the spirit of the invention.
